For an x-ray project need i 60kV from flyback because i havn´t an other source. the following pictures show my schematic. My question is, wich is right und wich is wrong ? I have not an idea !

Thank you. If i get the first x-ray pictures i will show it you.
Awesome.
Also just be aware that around 60kV-80kV is when these transformers typically start to break down and arc over so oil might be needed. You will probably be fine but its good to keep that in mind when you are using it in an application such as this and not just drawing arcs from it.

also, keep in mind the current you can put through a lopt. using zvs would be your best bet, and but i am not sure what these things typically draw. they usually require an iron core driven by mains, so i am skeptical/
You will definitly need oil otherwise the 30kv from the first one will arc to the core of the second one I don't think hot glue would be enough to stop that

If the colors mean that you are trying to cascade two transformers by connecting the HV terminal of one to the ground pin of the other, there is an extremely serious insulation problem on the idea. May work if the central connection is grounded and everything is under oil, but expect a disaster...

ok, didn't know that, but how much current can they source? surely much more than a typical lopt. keep in mind that the secondary built into these things uses ~30+ awg wire.

Photography runs in short bursts (generally) so heating is less of a problem compared to secondary breakdown. I've seen 60KW (peak) x-ray transformers roughly a cubic foot in size.
